I found a better and faster way to remove over 2500+ pages.
The other plugins would sometimes mark the episode as played which then caused me even more headaches. I downloaded iMacros for Chrome and I figured out this is the fastest and easiest way to remove duplicates.
Caution: I've turned on the ignore errors options so if something bad happens, such as duplicate plays, delete the SET !ERRORIGNORE YES line.
